title: An azygos vein aneurysm resected by video-assisted thoracic surgery after preoperative evaluation of multidetector computed tomography.
abstract: Azygos vein aneurysm is very rare and most cases are detected incidentally. We report a safe resection of azygos vein aneurysm by video-assisted thoracoscopic surgery (VATS) under preoperative evaluation of thrombus by multidetector computed tomography (MDCT). A 60-year old woman presented to our department due to a mediastinal mass revealed by enhanced CT. A dynamic enhanced-CT scan showed a dilated azygos vein with great enhancement in the early phase. Under the diagnosis of azygos vein aneurysm, we analysed the aneurysm by MDCT and confirmed that there was no thrombus within the aneurysm. The resection of the aneurysm by VATS was performed safely. She was discharged 4 days after surgery.
